Iimfuno ezintathu eziphambili zebhetri yokugcina amandla, ukhuseleko lolona lubalulekileyo
Ukugcinwa kwamandla e-electrochemical kuthathwa njengendlela ephambili yokugcina amandla kwinkqubo yamandla ezayo, ibhetri kunye ne-PCS lixabiso eliphezulu kunye nezithintelo kwi-chain chain chain, imfuno ephambili ilele kukhuseleko oluphezulu, ubomi obude kunye neendleko eziphantsi.Phakathi kwazo, ukhuseleko lungundoqo.Ezinye iingcali zeshishini zithe, ngoku indawo yokugcina amandla e-electrochemical ikhula ngokukhawuleza, kodwa umba wokhuseleko yingxaki yophuhliso lwawo olukhulu, indawo yokugcina amandla eBeijing kunye neTesla Australia iprojekthi yokugcina amandla yoqhushumbo nakwishishini lokugcina amandla. iye yakhala i alarm.
Ukuza kuthi ga ngoku, iimbono eziKhokelelwayo zokuKhawulezisa uPhuhliso lweSitorethi saMandla amatsha zibeka phambili ukusekwa kwemigangatho yeteknoloji yokhuseleko kunye nenkqubo yokulawula, ukomeleza ulawulo lokhuseleko lomlilo, ukuthobela ngokungqongqo umgca osezantsi wokhuseleko njengomgaqo osisiseko;kukhuseleko oluphezulu, ixabiso eliphantsi, ukuthembeka okuphezulu, ubomi obude kunye neminye imiba yenkqubela phambili;ukomeleza ukhuseleko lophando lweteknoloji yokugcina amandla e-electrochemical njalo njalo.IKhomishini yoPhuhliso lweSizwe kunye noHlaziyo, iBhodi yeSizwe yaMandla ukuba iququzelele ukuqulunqwa kwe "Imilinganiselo yeThutyana yoLawulo oluKhuselekileyo lwe-Electrochemical Energy Storage Stations (iDrafti)", nayo ibe ngo-Agasti 24 kuluntu ukuze kuboniswane noluntu, ukuqinisa ulawulo. yokhuseleko logcino lwamandla.
Ukhuseleko oluphezulu, ubomi obude, ibhetri ye-nickel-metal hydride ibalula
Idatha ye-China Battery Industry Association ibonisa ukuba i-nickel-metal hydride yombane yokhuseleko oluphezulu, ubomi bomjikelo omde, i-electrode yayo epholileyo eyenziwe ngama-nickel spheres, i-electrode negative esebenzayo imathiriyeli ixhaswa yi-hydrogen yokugcina i-alloy, iyeyezinto ezizinzileyo, i-electrolyte yamanzi ilungile. iipropathi zokubuyiswa komlilo, aziyi kuqhushumba kwaye zitshise iingozi, uxinano lwamandla ebhetri ukuya kuthi ga kwi-140wh/kg;ubomi bomjikelezo ukuya kuthi ga kwi-3,000, ukutshaja okunzulu kunye nokukhupha umjikelo welizwe ukuya kumaxesha angama-10,000 nangaphezulu;ingasetyenziselwa amaxesha angaphezu kwe-10,000;ingasetyenziselwa amaxesha angaphezu kwe-10,000.Ngamaxesha angaphezu kwe-10,000;inokugcina izinga eliphezulu lokutshaja kunye nokukhupha kwi -40°C ~ 60°C okusingqongileyo.I-Toyota HEV imoto yokuthengiswa kwemoto yehlabathi ifikelele ngaphezu kwe-18 yezigidi, kwaye ixhotyiswe ngokubanzi ngeebhetri ze-nickel-metal hydride, akuzange kubekho nanye imeko yeengozi zokutsha kwebhetri, ukhuseleko oluphezulu lwebhetri luqinisekisiwe ngokupheleleyo.
Ngaphezu koko, ukutshaja ibhetri kunye nokukhutshwa kukuguqulwa kwamandla ekhemikhali kunye namandla ombane, ubushushu bunempembelelo enkulu kwi-chemical reaction.Izikhululo zamandla okugcina amandla ubukhulu becala zingaphandle, uninzi lweentlobo zeebhetri zichaphazeleka kokusingqongileyo kunye nobushushu, ukukhawulela indawo yezikhululo zamandla kunye nokwenza buthathaka indima yokugcina amandla.Iibhetri ze-nickel-metal hydride kubushushu obuphantsi kakhulu kunye nobushushu obuphezulu bentlawulo egqwesileyo kunye nokukhupha ukusebenza kakuhle, ukuze indawo yokugcina amandla iguquguquke, ilunge ngakumbi, isebenze ngcono ngokubanzi, eye yaba kukuthatha inxaxheba kwayo kukhuphiswano lweendlela ezahlukeneyo zobuchwepheshe bebhetri " namanqaku".
Ngapha koko, iibhetri ze-nickel-metal hydride kwisicelo semarike yokugcina amandla ibe ngumzekelo.Ngo-2020, inkampani yokugcina amandla ebhetri ye-nickel-metal hydride iNilar yiBhanki yoTyalo-mali yaseYurophu i-47 yezigidi zee-euro zotyalo-mali.Kuyaqondwa ukuba i-Nilar igxininise ekudityanisweni kokuveliswa kwamandla okuvuselela kunye nokugcinwa, amandla okulinda kunye nezicelo zokutshaja isithuthi sombane, utyalo-mali kukukhuthaza inkampani iya kuhlanganiswa kwibhetri yendawo yokuhlala, yorhwebo kunye nezoshishino kunye negridi-scale okanye iinkqubo zemarike yeziseko. .Ngokutsho kweFrontiers kwiSayensi yePolymer, iqela likaNjingalwazi uYi Cui kwiYunivesithi yaseStanford liphuhlise ibhetri ye-nickel-metal hydride (Ni-MH) kumandla amakhulu avuselelekayo kunye nezicelo zokugcina, kunye neenzuzo zobomi benkonzo ye-ultra-long, akukho mngcipheko Ukubaleka komlilo okanye ubushushu, akukho mfuneko yokugcinwa kwesiqhelo, ukuziphatha okuhle kobushushu obuphantsi, kunye neendleko eziphantsi.Iqela likaCui liya kwakha iyunithi yokulinga enomthamo wokugcina we-megawatts ezi-2 ngo-2021, kwaye iceba ukwandisa umthamo wayo ukuya kuma-20 ngokuphindwe kabini loo mali ngo-2022.
